![]() Then In VS Code, open the Command Palette ( View > Command Palette or (Ctrl+Shift+P)). Then, we can open the folder “ venv_example” from the VS Code using the File > Open Folder command. Sudo apt-get install python3-venv # If needed Within this folder, we can create a virtual environment called “ myvenv” by running the following command: Create a Project Environmentįor this example, we call our project “ venv_example“, and we have created a folder with the same name. Finally, it is less risky to mess with your other projects when you work with virtual environments. This is because with the virtual environments, the project is reproducible, and we will need to install only the required libraries as stated in the requirements.txt. Moreover, it is more efficient to work with the necessary only libraries. When we work on a Data Science project, which can include a Flask API, it is better to have full control over the libraries used in the project. In this post, we will provide you a walk-through example of how to work with VS Code and virtual environments. You can run isort by opening the command palette ( CMD+SHIFT+P or CTRL+SHIFT+P), then typing "Python Refactor: Sort Imports".We have provided examples of how to work with conda environments. When you installed the Python extension for VSCode, you also unwittingly installed the isort extension which handles sorting imports. This makes it a bit easier to find the import you're looking for, if you have many of them. Within each of these three segments, it sorts imports alphabetically. Finally go imports from your own codebase. Then, go third-party libraries, like flask. Sorting the imports means that when you import a built-in library (e.g. It's especially useful if you are working on a codebase with other people. Sorting your imports may sound like a completely useless thing to do, but we do it for consistency. Import sorting with isort in Visual Studio Code Next, open your VSCode settings (with CMD+, or CTRL+,), and find the "Python Formatting Provider" setting. Then, install it using the console (make sure the console has the virtual environment activated too): pip install black To install black, make sure you've created a Python virtual environment and you've selected it in VSCode as your interpreter. Just install it, tell VSCode to run it, and you're good to go. I like the black formatter for Python because it has sane defaults, which means you don't have to configure it at all. Formatting with Black in Visual Studio Code Here's a link to the ruff repository and the extension repository in case you want to read up on it further. The easiest way to get it to work in Visual Studio Code is to install the Ruff extension. ![]() There are many linters in the Python ecosystem, but lately I've been favouring Ruff. Linting, formatting, and sorting imports with VSCode Linting with Ruff in Visual Studio CodeĪ linter is a tool that checks your code for common issues, and warns you if it finds any. Our article, "Working with virtual environments: the complete guide", will help you learn how to use virtual environments if you aren't familiar with them yet. You can change which version of Python the extension uses by clicking on the bottom right, where in the screenshot it says "Python 3.10.0".Īfter you create a virtual environment, which you should always do for each Python project you work on, you can choose it as the Python interpreter by clicking on the "Python 3.10.0" button. The Python extension gives you syntax highlighting and also helps you code by offering suggestions and hints. Once that's installed, you can open any folder using Visual Studio Code and create a file that ends in. There, look for the Python extension and install it: ![]() Open Visual Studio Code and navigate to the Extensions panel on the left hand side. And on Windows, make sure to tick the "Add Python to PATH" in the first screen of the official installer.ĭownload Visual Studio Code and install it like you would any other application. When you install Python (which I recommend you do via the official installer), remember in which folder you installed it. I'll also show you a few extensions that can make your life much easier while working with Python! Initial setup In this post we'll look at how to develop in Python using Visual Studio Code.
